Montemor-o-Novo Castle crowns the hill above the town, a great walled enclosure that is both the historic heart of Montemor and its finest viewpoint over the open Alentejo.
The castle has medieval origins; the town received its charter in the thirteenth century, under King Sancho I, on what was then the frontier with Muslim-held lands — hence the long circuit of walls. Within the enclosure stand the remains of a small town: the Churches of São João Baptista and Santiago, the ruins of the Church of Santa Maria do Bispo, and the Convent of Nossa Senhora da Saudação, along with three towers — the keep, the Clock Tower and the Torre da Má-Hora.
The town's most famous son, Saint John of God, founder of the Hospitaller Order, was born here in 1495. Much of the castle is now in ruins, but the walls, the surviving buildings and an interpretation centre can be visited freely, and the views over the Alentejo countryside are sweeping. It is classified as a National Monument.
